After allowing Arizona State quarterback Rudy Carpenter to throw for 361 yards and four touchdowns during a 44-32 loss in Tempe last weekend, the Oregon State defense knows it has to play better this Saturday against UCLA.

The Bruins (3-1 overall, 2-0 Pac-10) are coming off a 44-31 victory over Washington last Saturday and are averaging 44.5 point per game.

"We've got to be disciplined out there," said junior safety Al Afalava at Tuesday's press conference. "We didn't get burned by their receivers, they just got behind us. So we have to do better at staying in coverage."
